Instructions for Analyzing Data from CAHPS Surveys

CAHPS ® Surveys and Instructions
2. Recodes numeric plan variables to character to simplify
interpretation of the result tables.
length plan $ 16 ;
if planid = 1 then plan = ‘HMO_A_URBAN’ ;
else if planid = 2 then plan = ‘HMO_B_URBAN’ ;
else if planid = 7 then plan = ‘HMO_C_URBAN’ ;
else if planid = 4 then plan = ‘HMO_B_RURAL’ ;
else if planid = 5 then plan = ‘HMO_C_RURAL’ ;
else if planid = 6 then plan = ‘HMO_BE_1’ ;
3. Creates visits variable.
visits = q21 ;
4. Creates child variable by coding it to 0 for all surveys.
child = 0 ;
5. Recodes dichotomous variables from 1-2 to 1-0.
array yn q05 q13;
do i = 1 to dim ( yn ) ;
if yn [i] = 0 then yn [i] = . ;
else if yn [i] = 2 then yn [i] = 0 ;
end ;
6. REVERSE codes item in which never is a positive response and
always is a negative response.
array rev q24 ;
do i = 1 to dim ( rev ) ;
if rev [i] in (1, 2, 3, 4) then rev [i] = 5 - rev [i] ;
else rev [i] = . ;
end ;
7. Version 1.5 and higher of the CAHPS program does not automatically
clean case-mix adjustment variables as previous versions did because it
allows for a varying number and specification of the adjusters. If
adjusters are used in the analysis they must be cleaned first.
age = q40 ;
ghr = q39 ;
if ghr not in (1, 2, 3, 4, 5) then ghr = . ;
if age not in (1, 2, 3, 4, 5, 6, 7) then age = . ;
CAHPS41.SAS—Specifying Arguments and Options
The following statement includes the macro code CAHPS41.SAS.
%include cahps ;
The macro call statements for CAHPS41.SAS in CONTROL.SAS require that at least
six arguments, (VAR, VARTYPE, NAME, ADULTKID, DATASET, and
OUTNAME), be specified for it to work properly. These arguments, along with the
20 optional arguments, are listed in the table below with the valid value ranges. The
six arguments must be specified for each analytic run of the global ratings and
